S. boulardii is a probiotic strain and yeast that is beneficial in managing gastrointestinal (GI) issues and diarrhoea. But it also shows promise in helping with other conditions, such as heart functions and parasite infections. It is able to be taken while an animal is on antibiotics and research shows it can reduce the duration of time antibiotics are required.

Saccharomyces Boulardii is a gut-friendly yeast probiotic that is safe for dogs and cats. As a probiotic, it brings health benefits to the GI system and ultimately, the immune system.

Saccharomyces boulardii calms the intestines and protects them from pathogens and intruders that can damage the walls the intestines. It also modulates different parts of the immune system and helps maintain intestinal barrier function

In a recent trial, Saccharomyces boulardii addressed acute and chronic diarrhoea in dogs.
